Pfeiffer, in describing this species, cites as locality the Island of 

 Cuba. He says the shells were communicated to him by Menke, 

 and he gives as measurements: Length, 11 mm.; diameter, 7.5 mm. 

 This marks as the typical race the smaller of the two subspecies. 

 The name has usually been attached to the larger form. 



This race ranges from La Cidra eastward to the upper reaches of 

 the Canlmar Kiver past Limonar to the neighborhood of Matanzas. 

 Its smaller size, little broader outline, and little wider umbUicus will 

 differentiate it from A. (E.) limhvfera ternata Reeve. 



The specimen figured, U.S.N.M. No. 356576, comes from Limonar. 

 It has 5.2 whorls and measures: Length, 12.0 mm.; greater diameter, 

 9.5 mm.; lesser diameter, 7.1 mm. 



The animals of this subspecies, collected by Bartsch July 24, 1928, 

 on the paredones of the Rio Canimar below the central highway, 

 were described as follows: Animal short, smoke colored above; sides 

 of the body somewhat paler toward the edge of the foot; sole of the 

 foot the same color as this edge. Tentacles and eye ring flesh-colored, 

 the rest pale orange with buff suffusion, dark red at the tip. The 

 animal when in motion moves the shell along with a side wise jerk, 

 which gives it the appearance of progressing by a series of jumps. 

 This species appears to range eastward through Cardenas to Sagua 

 La Grande, Santa Clara Province. 



ANNULARIA (EUTUDORA) TRANSITORIA. new species 



Shell trochoid, flesh colored, with interrupted spiral bands of brown, 

 which are rather closely spaced; these are present on spire and base. 

 The elements composing these bands are arranged in both axial and 

 spiral series. The peristome is white; the interior of the aperture is 

 almost white. Nuclear whorls 2, well rounded, microscopically 

 granulose, except the last portion of the last whorl, which shows 

 the beginning of the postnuclear sculpture. Postnuclear whorls 

 inflated, strongly rounded, marked by very strong lamellar spiral 

 cords; the first of these is rendered slightly crenulated by indications 

 of axial riblets near the summit. Suture strongly channeled. Pe-
